The present invention relates to o-trifluoromethyl-m'-isopropoxybenzoic acid anilide (hereinafter, compound A).
) and 4-methylsulfonyloxyphenyl-N-methylthiol carbamate (hereinafter referred to as compound B) or N-(1-n-butoxy-
The present invention relates to a soil disease control agent for agricultural and horticultural use, which contains 2,2,2-trichloroethyl)-2-hydroxybenzamide (hereinafter referred to as compound C) as an active ingredient. Compound A is a known compound described in the specification of JP-A-53-9739, and is mainly effective against rice sheath blight. Moreover, compound B and compound C are each JP-A-53-
It is a known compound described in No. 47527 and JP-A-54-39040, and has activity as a soil disease control agent. As a result of research on soil disease control agents, the present inventors have recently found that rice seedling damping-off, vegetable seedling damping-off, cucumber damping-off, eggplant half-wilt, strawberry bud blight, and strawberry root rot. The control agent containing Compound A and Compound B or Compound C as active ingredients is more effective against soil diseases such as radish crack browning, wheat snow rot, brown patch, and spring baldness than using each agent alone. It was also found that the insecticide has an extremely high pesticidal effect. Among these soil diseases, the control agent containing Compound A and Compound B as active ingredients is effective against snow rot of wheat and turf, especially Fusarium.
It has a synergistic effect compared to the effects of each agent alone against the fungal-induced red snow rot. In addition, the control agent containing Compound A and Compound C as active ingredients has a synergistic effect on radish crack browning disease, especially the disease caused by Aphanomyces, compared to the effects of each agent alone. It has a great effect. To produce a soil disease control agent containing Compound A and Compound B or Compound C as active ingredients, both components are mixed with a carrier (diluent) according to a conventional method for agricultural chemical formulations, and if necessary, the desired amount is added. Auxiliary agents such as surfactants, dispersants, fixing agents, etc. may be added to form a dosage form convenient for use, such as powders, emulsions, floor pulls, tablets, wettable powders, microgranules, granules, etc. . The present invention is based on the fact that the combined use of Compound A and Compound B or Compound C is highly effective in controlling soil diseases. Embodiments in which the two are used together also belong to the scope of the present invention. The blending ratio of Compound A and Compound B or Compound C can be adjusted as necessary, but it is convenient to select it as appropriate from the range of 6:1 to 1:10. The appropriate proportion of the active ingredient compound in the formulation is usually 0.5 to 20% (by weight) in the case of powders or granules, and 10 to 50% (by weight) in the case of emulsions or wettable powders. The present invention includes embodiments in which it is applied prophylactically or therapeutically to the above-ground parts of crops to be protected, either directly or via a soil. The amount of the pest control agent of the present invention to be used varies depending on various factors such as the degree of damage, tendency of occurrence, weather, environmental conditions, dosage form, etc. For example, when ultimately used in liquid form, such as an emulsion or a wettable powder, the final concentration of the active ingredient may generally be 0.01% (by weight) or more. In addition, when using it as it is as a powder or granule, it is sufficient to spray 50 g or more of the active ingredient per 10 ares. In addition, the pesticidal agent of the present invention may be mixed with other herbicides, insecticides, soil disease control agents, fungicides, fertilizers, etc.
It is also possible to expand the scope of application of the pesticidal agent of the present invention. Next, some examples will be listed, but the present invention is not limited to these examples. In addition, “department”
indicates parts by weight. Example 1 Compound A 1 part Compound B (or Compound C) 0.5 parts White carbon 1 part PAP (isopropyl acid phosphate: manufactured by Nippon Kagaku Co., Ltd.) 0.3 parts Clay 97.2 parts were uniformly mixed and ground to form a powder. Example 2 Compound A 24 parts Compound B (or Compound C) 6 parts Xylene 55 parts Polyoxyethylene alkyl allyl ether 15 parts were uniformly mixed and dissolved to prepare an emulsion. Example 3 Compound A 22 parts Compound B (or Compound C) 8 parts White carbon 20 parts Sodium dodecylbenzenesulfonate 5 parts Clay 45 parts were uniformly mixed and pulverized to prepare a wettable powder. Example 4 Compound A 8 parts Compound B (or Compound C) 7 parts Polyvinyl alcohol 2 parts White carbon 5 parts Sodium dodecylbenzenesulfonate 0.2 parts Clay Mix and grind 77.8 parts, add 18 parts of water, knead, and extrude granulate. The product is granulated and dried using a machine to form granules. Next, test examples of the present invention will be shown. Test Example 1 Wheat snow rot control test A wettable powder of the present invention formulated in the same manner as in Example 3 was applied to a wheat (variety: white wheat) field where red snow rot (pathogenic bacterium Fusarium nivale) frequently occurs. A predetermined amount of the material was sprayed using a pressurized sprayer just before the ground snow fell. The area per ward was 15m2 . After the snow melted, the disease was investigated by disease index, and the disease severity was calculated using the following formula to determine the control value. Disease severity = Σ (sickness index × number of applicable strains) / number of investigated strains × 4 ×
100 Disease index 4: Complete withering 3: Half of all leaves and stems are dead 2: All leaves and some of stems are withered 1: Half of leaves are withered 0: Healthy Control value (%) = Disease severity of untreated plant - treated area Incidence level/Intensity of untreated disease x 100 The test results are shown in Table 1.

The area of ward 1 was 18m2 . On the 33rd day after sowing, daikon radish plants were taken out and disease onset was investigated according to severity. The disease severity was calculated using the following formula and the control value was determined. Severity of disease = 3n 3 +2n 2 +n 1 /3N n 1 : Number of plants with disease attack area rate of 1% or less n 2 : Number of plants with disease attack area rate of 1% to 3% n 3 : Number of plants with disease attack area rate of 3% or more N: Number of investigated plants Control value (%) = disease severity in untreated area - disease severity in treated area/ disease severity in untreated area x 100 The test results are shown in Table 2.
